I wonder if you would feel the same way if, in 1956 they had felt as you do. You would not have computers. You would not have internet. You would not have refrigeration technology that is clean, self contained and safe. You would not have "freeze dried" foods, you would not have satelites, or geo-imaging. You wouldn't have super sonic aircraft. Among the many other things you would not have today, if it were not for the cold war and the space program.
I understand your point, it's time to get the budget under control, however, I think we could probably just stop going to war half way around the world and get that handled just fine. In fact, I have proposal. End all active US occupations, reroute all the personnel and money into space projects, including "fuel scooping" from stars or gas giants. All the hydrocarbons or heavy elements you could possibly use in 100 generations are sitting out there just waiting for someone to take them. Not only would this give our military the continued and further "edge" that makes them the "best". (you want orbital insertion drop ships, admit it) But it also means that the silly oil reserves in the middle east are worthless and tiny when taken against the vast resources of Jupiter and her moons.
OR, you can continue to decry space funding, while enjoying your position on top of the world... until the resources really do start to get thin, and then what? WAR. And if you are very very lucky, China will be on your side. If you aren't, your country might survive long enough to become a third world hell hole. By which point it will be too late to get into space, because morons without any foresight decided that it was a waste of money when there were more pressing humanitarian needs. FFS. They aren't mutually exclusive. In fact, large portions are inclusive. But I don't figure the people here complaining about space funding are likely to grasp that.
